The ReCAna for Lower ExtremIty Venous OBstructions and In-StEnt Restenosis Registry

The goal of this observational study is to gather additional safety and performance (effectiveness) data on the device for the treatment of symptomatic lower extremity venous obstructions and occlusions. The main questions the study aims to answer are: * What is the observed rate of safety events through the 30-day follow-up? * What is the rate of technical success (acute procedural success) achieved at the index procedure? Participants already undergoing treatment with the Recana as part of their regular medical care will be followed for 1 year.
